\subsection{Wi-Fi Sniffer Mode}
Esp32 can be setup in a ``sniffer mode''. Following packets can be dumped to the application:
\begin{list}{-}{}
\item 802.11 Management frame.
\item 802.11 Data frame, including MPDU, AMPDU, and AMSDU.
\item 802.11 MIMO frame, for MIMO frame, the sniffer only dumps the length of the frame.
\item 802.11 Control frame.
\item 802.11 CRC error frame.
\end{list}
The same can be done with the esp8266 as described in this article:
